Antibiotics are widely used in animal production for treating the diseases and for preventing or increasing animal growth. The presence of antibiotic residues in milk is a public health problem. The aim of this study was to assess the use of antibiotic residues in raw milk from the dairy pool of Niamey in three farms (Toukounous, Kirkissoye, and Niamey) and three collection centers (Hamdallaye, Kollo, and Say).
A direct interview (questionnaire) was used to collect data regarding the mode of use of antibiotics, the level of knowledge of farmers according to the withdrawal period, and a cross-sectional study was conducted on 192 samples of raw milk. The Delvotest T was used to monitor antibiotic residues in milk. The data were analyzed using SAS and R software.
The most commonly used antibiotics were those from the family of tetracycline (86.7%) and from the family of beta-lactams (13.3%). Regarding the statements of farmers, the reasons why the farmers use antibiotics were the following: About 47% in case of prevention and treatment, 29% for treatment, 12% for prevention, and 12% for increase dairy production. Moreover, the farmers lacked the necessary information about withdrawal period. Screening of antibiotic residues was performed using a standardized biological test kit, the Delvotest. In total, from 192 samples of raw milk, 19 (9.9%) were positive including ten from collection centers and nine from farms. This could lead to a risk of exposure when a consumer drinks locally produced raw milk.
Raw milk supplied from the area of the study has a level of antibiotic residues, and the breeders have a low level of knowledge about the withdrawal period.
抗生素在动物生产中被广泛用于治疗疾病以及预防或促进动物生长。牛奶中抗生素残留的存在是一个公共卫生问题。本研究的目的是评估尼亚美三个农场（图库努斯、基尔基索耶、尼亚美）和三个收集中心（哈姆达莱耶、科洛、赛伊）的乳制品库中原料奶抗生素残留的情况。
采用直接访谈（问卷）收集有关抗生素使用方式、农民对休药期的了解程度的数据，并对192份原料奶样本进行横断面研究。使用德尔伏测试T来监测牛奶中的抗生素残留。数据使用SAS和R软件进行分析。
最常用的抗生素是四环素类（86.7%）和β-内酰胺类（13.3%）。关于农民的说法，农民使用抗生素的原因如下：预防和治疗占约47%，治疗占29%，预防占12%，提高乳制品产量占12%。此外，农民缺乏关于休药期的必要信息。使用标准化生物检测试剂盒德尔伏测试进行抗生素残留筛查。总共，在192份原料奶样本中，19份（9.9%）呈阳性，其中10份来自收集中心，9份来自农场。当消费者饮用当地生产的原料奶时，这可能导致接触风险。
研究区域供应的原料奶存在抗生素残留水平，养殖户对休药期的了解程度较低。
